Kevin Colwell 171 Posted February 22, 2012 Share Posted February 22, 2012 Hello Everyone, we all (or most) use epoxy as a sealant and secondarily as a way to hold things together. I have heard that epoxy expands and also contracts with age. Of course, these are huge generalizations because I wasn't given or seeking info about what type of expoxy and where it was aging, etc. However, to help gain a little understanding, I did some internet researching. This paper came up, and it provides a fairly good description of the changes in mechanical and chemical properties of epoxy over time. Especially interesting, to me, was the stuff about change in volume, viscosity, elasticity, and strength. I fear I will screw things up if I try to translate. Here is the link. http://www.me.mtu.edu/~gmodegar/papers/J_Polymer_Sci_B_2011_pp.pdf Enjoy the reading. take care, Kevin please visit my website http://www.professorsforge.com/ “Years ago I recognized my kinship with all living things, and I made up my mind that I was not one bit better than the meanest on the earth. I said then and I say now, that while there is a lower class, I am in it; while there is a criminal element, I am of it; while there is a soul in prison, I am not free.” E. V.
